TECHNICAL FIELD

BACKGROUND

In general, a heating system is applied to a heating appliance whichburns gas or the like and heats air, thus performing heating controldepending on an operation environment. As an example, the heatingappliance may correspond to an air handling unit or the like.

Such a heating system determines a supply air setting temperaturedepending on a ventilation temperature, circulating air volume, and thecapacity of the heating system and performs heating control based on thedetermined supply air setting temperature.

As a ventilation temperature increases when heating is continuouslyperformed, because a supply air temperature increases together, aheating system which does not subdivide calorific adjustment repeatsON/OFF at a short period as the supply air temperature reaches a supplyair setting temperature in a short time. As such, when the heatingsystem repeats ON/OFF at the short period, heating performance of theheating system may be degraded and durability of a part or the like maybe degraded.

Meanwhile, a heating system which subdivides calorific adjustment maycontinuously perform burning for heating with low calorie. However, whenthe heating system continues performing burning for a long time,durability of a burner or the like may be degraded.

FIG. 1 is a block diagram illustrating a configuration of a heatingsystem according to an embodiment of the present disclosure.

The heating system may collect state information in real time or at acertain period while a heating appliance performs heating control tomonitor the collected state information, may compare a heating burningtime of the heating appliance with a predetermined allowable burningtime based on the identified state information, and may variably controla supply air setting temperature of the heating appliance depending onthe compared result. As an example, the heating appliance may be an airhandling unit having a heating function.

Referring to FIG. 1 , a heating system 100 may include a controller 110,a communication device 120, storage 130, and a state monitoring device140.

The controller 110 may be a hardware device, such as a processor or acentral processing unit (CPU), or may be a program implemented by aprocessor. The controller 110 may be connected with respectivecomponents of the heating system 100 to perform an overall function forcontrolling a supply air temperature.

The communication device 120 may receive state information obtained bysensors while the heating appliance is running. As an example, the stateinformation may include information such as a ventilation temperature,circulating air volume, or a heating burning time.

The storage 130 may store data, an algorithm, and/or the like necessaryfor an operation of the heating system 100. As an example, the storage130 may store state information of the heating appliance, which isreceived from respective sensors while the heating appliance isoperating. Furthermore, the storage 130 may store conditionspredetermined for controlling a supply air temperature of the heatingappliance, an algorithm, and/or the like.

Herein, the storage 130 may include a storage medium such as a randomaccess memory (RAM), a static RAM (SRAM), a read-only memory (ROM), aprogrammable ROM (PROM), or an electrically erasable PROM (EEPROM).

When the heating control of the heating appliance starts, the statemonitoring device 140 may monitor state information received through thecommunication device 120 in real time. Herein, monitoring the stateinformation in real time may include monitoring the state information atintervals of a predetermined certain time period, other than monitoringthe state information in a continuous time.

As an example, when heating control starts, the state monitoring device140 may monitor a heating burning time while heating burning control inone cycle is performed in real time. Furthermore, when the heatingburning control in the one cycle ends, the state monitoring device 140may monitor a total heating burning time during the cycle.

The controller 110 may control an operation of the state monitoringdevice 140 when the heating control starts and may variably control asupply air setting temperature when the monitored result of the statemonitoring device 140 meets a supply air temperature compensationcondition.

As an example, when the heating burning time while the heating burningcontrol in the one cycle is performed is greater than a predeterminedallowable burning time, the controller 110 may determine that a firstcondition for supply air temperature compensation is met. In this case,the controller 110 may upwardly adjust the supply air settingtemperature.

Herein, the allowable burning time refers to a time when continuousburning is allowed upon heating burning. When the allowable burning timeis set to a certain time range, the controller 110 may determine whetherthe heating burning time while the heating burning control in the onecycle is performed is greater than a maximum time (or a maximumallowable burning time) in the certain time range set to the allowableburning time. While the heating burning time during the one cycle isgreater than the predetermined allowable burning time, because a problemin a burner or the like is able to occur as burning continues for a longtime, a heating burning time should be reduced.

Thus, when the supply air setting temperature is upwardly adjusted, aheating burning time may be shortened as a supply air temperatureincreases upon heating burning.

The controller 110 may perform supply air temperature compensation withrespect to a time point when the heating burning time is greater thanthe predetermined allowable burning time while the heating burningcontrol in the one cycle is performed.

At this time, the controller 110 may upwardly adjust the supply airsetting temperature by a correction temperature and may then identifywhether heating burning ends during a predetermined time T. When theheating burning does not end during the predetermined time T afterupwardly adjusting the supply air setting temperature by the correctiontemperature, the controller 110 may upwardly adjust the supply airsetting temperature by the correction temperature again. In such amanner, the controller 110 may upwardly adjust the supply air settingtemperature by the correction temperature at intervals of thepredetermined time T until the heating burning the cycle ends.

When the heating burning ends, the controller 110 may stop the supplyair temperature compensation such that heating burning in a next cycleis performed by the heating appliance after a certain time elapses.

Thus, a description will be given in detail of a supply air temperaturecompensation operation for upwardly adjusting the supply air settingtemperature with reference to an embodiment of FIG. 2 .

FIG. 2 is a drawing referenced to describe an operation of controlling asupply air temperature of a heating system according to an embodiment ofthe present disclosure. The embodiment of FIG. 2 indicates a supply airtemperature compensation operation for upwardly adjusting a supply airsetting temperature.

Referring to FIG. 2 , t1 refers to a heating burning time identifiedduring heating burning in a first cycle, and t2 refers to a heatingburning time in a second cycle. Assuming that t2 is a predeterminedallowable burning time, t1 is greater than the allowable burning time.

When the heating burning time is greater than the allowable burningtime, a problem in a burner or the like may occur due to burning for along time. Thus, a controller 110 of FIG. 1 may compensate for a supplyair setting temperature during burning to prevent a heating burning timein one cycle from being greater than the allowable burning time.

As an example, the controller 110 may identify the heating burning timet1 in real time during heating burning in the first cycle and mayupwardly adjust a supply air temperature by a correction temperature tocompensate for the supply air setting temperature, when the identifiedheating burning time t1 is greater than the predetermined allowableburning time. At this time, when the supply air setting temperature isupwardly adjusted, a heating burning time may be shortened as a supplyair temperature increases.

When the heating burning does not end although a predetermined time Telapses after upwardly adjusting the supply air setting temperature, thecontroller 110 may upwardly adjust the supply air setting temperature bythe correction temperature again. Herein, T is a predetermined time,which refers to a supply air temperature compensation period. As anexample, T may be a time of an optimal period obtained to variablycontrol a supply air setting temperature through a pre-test or the like.

In the embodiment of FIG. 2 , the controller 110 may identify thatheating burning ends after upwardly adjusting the supply air settingtemperature two times during 2T after a time point when the heatingburning time t1 identified during the first cycle is greater than theallowable burning time.

Thereafter, the controller 110 may perform a heating burning operationbased on the supply air setting temperature previously set during thefirst cycle in the second cycle, thus identifying that the heatingburning time decreases by t2 from t1.

At this time, because the heating burning time t2 in the second cyclecorresponds to the predetermined allowable burning time, the controller110 does not compensate for the supply air setting temperature andstarts heating control in a next cycle after a certain time when thesecond cycle ends.

As another example, when heating burning control in one cycle ends, thecontroller 110 may identify a heating burning time monitored by a statemonitoring device 140 of FIG. 1 . When a final heating burning timeduring the cycle is less than the allowable burning time after the cycleends, the controller 110 may determine that a second condition forsupply air temperature compensation is met. In this case, the controller110 may downwardly adjust the supply air setting temperature.

Herein, the allowable burning time refers to a time when continuousburning is allowed upon heating burning. When the allowable burning timeis set to a certain time range, the controller 110 may determine whetherthe final heating burning time is less than the allowable burning timewith respect to a minimum time in the certain time range set to theallowable burning time. When the heating burning time during one cycleis less than the predetermined allowable burning time, as ON/OFF isfrequently repeated upon heating, a problem in durability of the systemmay occur and heating efficiency is able to be degraded due to this. Inthis case, the controller 110 should increase the heating burning time.

Thus, when the supply air setting temperature is downwardly adjusted, asthe supply air temperature decreases upon heating burning, the heatingburning time may increase.

Thus, after heating burning in one cycle ends, when the heating burningtime during the cycle is less than the predetermined allowable burningtime, the controller 110 may perform supply air temperaturecompensation.

At this time, the controller 110 may downwardly adjust the supply airsetting temperature by a correction temperature, such that heatingburning control is performed based on the downwardly adjusted supply airsetting temperature when a next cycle starts.

Thereafter, when the heating burning in the next cycle ends, thecontroller 110 may identify a heating burning time during the cycle andmay perform supply air temperature compensation again when theidentified heating burning time is less than the predetermined allowableburning time. At this time, the controller 110 may downwardly adjust thesupply air setting temperature by the correction temperature, such thatheating burning control is performed based on the downwardly adjustedsupply air setting temperature when a next cycle starts.

Of course, after the heating burning in the next cycle ends, when theheating burning time during the cycle is greater than or equal to thepredetermined allowable burning time, the controller 110 does notperform supply air temperature compensation.

Thus, a description will be given in detail of a supply air temperaturecompensation operation for downwardly adjusting the supply air settingtemperature with reference to an embodiment of FIG. 3 .

FIG. 3 is a drawing referenced to describe an operation of controlling asupply air temperature of a heating system according to anotherembodiment of the present disclosure. The embodiment of FIG. 3 indicatesa supply air temperature compensation operation for downwardly adjustinga supply air setting temperature.

Referring to FIG. 3 , t1 refers to a heating burning time in a firstcycle, t2 refers to a heating burning time in a second cycle, and t3refers to a heating burning time in a third cycle. Assuming that t3 is apredetermined allowable burning time, t1 and t2 do not even reach theallowable combustion time.

As such, when the heating burning time during one cycle is less than theallowable burning time, as ON/OFF is frequently repeated during heatingcontrol, this causes a durability problem of the system and heatingefficiency may be degraded due to this. Thus, the controller 110 maycompensate for a supply air setting temperature after a burning controloperation in one cycle ends to prevent ON/OFF from being frequentlyrepeated as the heating burning time during the one cycle is less thanthe allowable burning time.

As an example, the controller 110 may identify a heating burning time t1after heating burning during the first cycle ends and may downwardlyadjust the supply air setting temperature by a correction temperature tocompensate for the supply air setting temperature, when the identifiedheating burning time t1 is less than the predetermined allowable burningtime. At this time, when the supply air setting temperature is upwardlyadjusted, as a supply air temperature decreases, a heating burning timemay increase.

When the second cycle starts after downwardly adjusting the supply airsetting temperature, the controller 110 may identify the heating burningtime t2 after heating burning during the second cycle ends. Thereafter,the controller 110 may perform a heating burning operation based on thesupply air setting temperature previously set during the first cycle inthe second cycle, thus identifying that the heating burning timeincreases by t2 from t1.

However, when the heating burning time t2 identified during the secondcycle is less than the predetermined allowable burning time, thecontroller 110 may downwardly adjust the supply air setting temperatureby the correction temperature again to compensate for the supply airsetting temperature. At this time, when the supply air settingtemperature is downwardly adjusted, as the supply air temperaturedecreases, the heating burning time may further increase.

Likewise, when the third cycle starts after downwardly adjusting thesupply air setting temperature, the controller 110 may identify theheating burning time t3 after heating burning during the second cycleends. In this case, the controller 110 may perform a heating burningoperation based on the supply air setting temperature previously setduring the second cycle in the third cycle, thus identifying that theheating burning time increases by t3 from t2.

At this time, because the heating burning time t3 in the third cyclecorresponds to the predetermined allowable burning time, the controller110 does not compensate for the supply air setting temperature andstarts heating control in a next cycle after a certain time.

A description will be given in detail of operational flow of the heatingsystem according to an embodiment of the present disclosure, having theabove-mentioned configuration.

FIG. 4 is a drawing illustrating operational flow of a method forcontrolling a supply air temperature of a heating system according to anembodiment of the present disclosure. The embodiment of FIG. 4 indicatesa control operation when a heating burning time is greater than apredetermined allowable burning time.

Referring to FIG. 4 , when burning starts depending on a heating requestin S110, a heating system 100 of FIG. 1 may identify a heating burningtime in real time. At this time, the heating system 100 may identify theheating burning time at intervals of a certain time. Herein, the heatingsystem 100 may continue identifying the heating burning time until theheating burning ends.

The heating system 100 may determine whether the heating burning time isgreater than the predetermined allowable burning time. Because a problemin a burner or the like is able to occur when burning continues to begreater than the allowable burning time, the heating system 100 maycontinue determining whether the heating burning time is greater thanthe allowable burning time while the heating burning continues. Herein,the allowable burning time refers to a time when continuous burning isallowed, which may be set to a specific time value or may be set to acertain time range. When the allowable burning time is set to thecertain time range, the heating system 100 may determine whether theheating burning time is greater than the allowable burning time withrespect to a maximum time in the certain time range set to the allowableburning time while heating burning in one cycle continues.

When the heating burning time is not greater than the allowable burningtime in S120, the heating system 100 may continue performing S120 untilthe heating burning ends.

Meanwhile, when the heating burning time identified during the heatingburning is greater than the allowable burning time in S120, in S130, theheating system 100 may upwardly adjust a supply air setting temperatureby a correction temperature. At this time, when a supply air temperatureincreases, because the heating burning time is able to be shortened bythe increased supply air temperature, the heating system 100 mayupwardly adjust the supply air setting temperature by the correctiontemperature to shorten the heating burning time. Herein, the correctiontemperature may be a predetermined value.

The heating system 100 may perform heating control based on the supplyair setting temperature upwardly adjusted in S130. Thereafter, when theheating burning ends within a predetermined time T in S140 to S160, therelated operation may end.

Meanwhile, after S130, when the heating burning does not end during thepredetermined time T, in S130, the heating system 100 may upwardlyadjust the supply air setting temperature previously set in S130 by thecorrection temperature again. Herein, the predetermined time T may be atime of an optimal period obtained to variably control the supply airsetting temperature through a pre-test or the like. Thereafter, theheating system 100 may perform heating control based on the supply airsetting temperature upwardly adjusted by the correction temperature.

As such, the heating system 100 may upwardly adjust the supply airsetting temperature by the correction temperature at intervals of thepredetermined time T until the heating burning ends. Thereafter, whenthe heating burning ends in S150 and S160, the heating system 100 mayend a heating control operation in the cycle.

The process of S110 to S160 may correspond to a heating burningoperation in one cycle during the heating control. When a heatingburning operation in a next cycle starts after a certain time elapses,the process of S110 to S160 may be repeatedly performed again.

As the embodiment of FIG. 4 , when the heating burning time continuesfor a long time, the heating system 100 according to an embodiment ofthe present disclosure may upwardly adjust the supply air settingtemperature to reduce the heating burning time, thus preventing theburner or the like from being damaged.

FIG. 5 is a drawing illustrating operational flow of a method forcontrolling a supply air temperature of a heating system according toanother embodiment of the present disclosure. The embodiment of FIG. 5indicates a control operation when a heating burning time is less than apredetermined allowable burning time.

Referring to FIG. 5 , in S210, a heating system 100 of FIG. 1 may startburning depending on a heating request. Thereafter, after heatingburning in one cycle ends in S220, the heating system 100 may identify aheating burning time during the one cycle. Herein, the heating system100 may identify the heating burning time until the heating burning endsafter the heating burning starts.

At this time, the heating system 100 may determine whether the heatingburning time is less than the predetermined allowable burning time. Whenheating burning in one cycle ends less than the allowable burning time,as ON/OFF is frequently repeated during heating control, because thiscauses a durability problem of the system and heating efficiency is ableto be degraded due to this, the heating system 100 may determine whetherthe heating burning time during the one cycle is less than the allowableburning time whenever the heating burning in the cycle ends. Herein, theallowable burning time refers to a time when continuous burning isallowed, which may be set to a specific time value or may be set to acertain time range. When the allowable burning time is set to thecertain time range, the heating system 100 may determine whether theheating burning time is less than the allowable burning time withrespect to a minimum time (or a minimum allowable burning time) in thecertain time range set to the allowable burning time after the heatingburning in the one cycle ends.

When the heating burning time is not less than the allowable burningtime in S230, the heating system 100 waits until heating burning in anext cycle starts.

Meanwhile, when the heating burning time is less than the allowableburning time in S230, in S240, the heating system 100 may downwardlyadjust a supply air setting temperature by a correction temperature toincrease the heating burning time to be longer. At this time, when asupply air temperature decreases, the heating burning time is able toincrease by the decreased supply air temperature, the heating system 100may downwardly adjust the supply air setting temperature by thecorrection temperature to increase the heating burning time to belonger. Herein, the correction temperature may be a predetermined value.

Thereafter, the heating system 100 may perform control in S210 to S240based on the supply air setting temperature downwardly adjusted by thecorrection temperature in a next cycle.

Even upon the heating control in the next cycle, when the heatingburning time during the cycle is less than the allowable burning time,the heating system 100 may downwardly adjust the supply air settingtemperature by the correction temperature again.

As the embodiment of FIG. 5 , when the heating burning time in one cycleis too short, the heating system 100 according to an embodiment of thepresent disclosure may downwardly adjust the supply air settingtemperature to increase the heating burning time, thus preventing anON/OFF operation upon heating control from being frequently repeated.

According to an embodiment of the present disclosure, the heating systemmay follow an allowable burning time and may variably control a supplyair setting temperature of a heating appliance, thus preventing ON/OFFfrom being repeated at a short period or preventing burning fromcontinuing for a long time with low calorie to improve heatingperformance and durability.

Furthermore, according to another embodiment of the present disclosure,the heating system may perform heating control irrespective of a changein a heating environment element.
